Thread Title: Getting set to build a laser pointer here

pfred,

Your schematic is looking good.  Glad to see you did not put a capacitor on the output since you are using it for a constant current regulator.  Some people say to put them on there to stabilize things, but you should not have one when using it as a current regulator.

I can't wait to see your project when it is done.

What voltage is your laser diodes you are getting?  If you have time to wait...here are some that I bought..but they are in china and will take a little while to arrive....

The Operating Voltage is 3V and the Operating Current is < 45 mA....just a thought.

Thread Title: Tinker Playground Tutorials?

This site does not use any framework and no part of it is a commercial package.  From the projects to the blog to the forum.  It was all hand coded one line at a time.  I was wondering if anyone would want me to do a tutorial series on how I made each section.  I could do a series of tutorials for the projects section, the blog, and a forum....if you are interested, please post a response and if enough people want it, i will get to work on it.  Let me know.
